How to find the length of the shortest word in a string with Rust

Answer 1

fn shortest_word_length(text: &str) -> usize {
    // split_whitespace handles all whitespace and ignores empty segments
    let words = text.split_whitespace();

    // Find the minimum length, or return 0 if no words exist
    words.map(|w| w.len()).min().unwrap_or(0)
}

fn main() {
    let input = "Find the shortest word length in this string";
    let result = shortest_word_length(input);

    if result == 0 {
        println!("No words found.");
    } else {
        println!("Length of the shortest word: {}", result);
    }
}



/*
run:

Length of the shortest word: 2

*/
